Randomized Controlled Trial Comparative Study
Effectiveness of intravenous lidocaine versus intravenous morphine for patients with renal colic in the emergency department.
Despite the fact that numerous medications have been introduced to treat renal colic, none has been proven to relieve the pain rapidly and thoroughly. In this study, we aimed at comparing the effects of intravenous lidocaine versus intravenous morphine in patients suffering from renal colic. ⋯ Changing the smooth muscle tone and reducing the transmission of afferent sensory pathways, lidocaine causes a significant reduction in pain.
